Price , Mined Land Reclamation Division 423 Centennial Building ,_ _ 1313 Sherman Street - ` '•~ Denver, CO 80203 Re: 1985 Annual Hydrology Report Dear Randy: The Bear Coal Company, Inc., hereby submits our Annual Hydrology Report for 1985, for the Bear Number Three Mine. On November 8, 1985, the Colorado Mined Land Reclamation • Division approved a technical revision to our mining permit which allows Bear to discontinue monitoring alluvial well AA2. In ad- dition the revision reduces the frequency of monthly sampling to quarterly sampling, and calls for an annual water sample from each well be tested by a laboratory instead of quarterly as had been done before. In accordance with this revision, Bear Coal Company did not make alluvial well field tests in the month of December, 1985, nor was a sample submitted to a laboratory for testing in the 4th quarter of 1985. Therefore, please find the following: (a) Alluvial Well field test results for the period January thru November, 1985. (b) Quarterly alluvial well sample results for the first three quarters of 1985. As you are aware, due to it's location, the Bear Coal Com- pany was forced to suspend sampling of alluvial well AA2 begin- ning in March of 1985. During the year, there was a discharge from our sediment pond on March 23, 1985. This discharge was caused by an unusually rapid spring snow melt. We do not anticipate that this will be a problem in the future, and a copy of our report to the • Colorado Department of Health is enclosed. Bear Coal Company management estimates that our operation consumed approximately 700,000 gallons of water in 1985. During 1985, there were no outflows from the Bear Number Three Mine. .'- i.
